Nephrocalcinosis causes RENAL INSUFFICIENCY.Rumen: The first stomach of ruminants. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. The rumen is lined by mucous membrane containing no digestive glands, but mucus-secreting glands are present in large numbers. Coarse, partially chewed food is stored and churned in the rumen until the animal finds circumstances convenient for rumination. When this occurs, little balls of food are regurgitated through the esophagus into the mouth, and are subjected to a second more thorough mastication, swallowed, and passed on into other parts of the compound stomach.

Hypokalaemic paralysis revealing Sjogren syndrome in an elderly man. (1/246)

A 73 year old white man presented with life threatening hypokalaemic paralysis requiring admission to an intensive care unit. Biochemical investigations showed severe hypokalaemia with hyperchloraemic metabolic acidosis, a spot urine pH of 6.5, and a positive urinary anion gap, establishing the diagnosis of distal renal tubular acidosis. Autoimmune tests revealed Sjogren syndrome as the underlying cause of the distal renal tubular acidosis. Full recovery followed potassium and alkali replacement. This dramatic presentation of Sjogren syndrome has not previously been reported in an elderly man.  (+info)

The occurrence of renal involvement in primary Sjogren's syndrome: a study of 78 patients. (2/246)

OBJECTIVE: To ascertain the occurrence of renal involvement in patients with primary Sjogren's syndrome (pSS). METHODS: Urinary total protein excretion from 24 h urine collection, as well as urinary excretion rates of albumin, alpha-1 microglobulin (alpha1m) and IgG from overnight 8 h collections, were determined from 78 pSS patients (75 females, three males). Urine acidification capacity after oral ammonium chloride load was tested in 55 of these patients. RESULTS: Mild proteinuria (0.15-0.42 g/24 h) was observed in 34 patients (44%). Increased urinary excretion rates of albumin (>/=20 microgram/min), alpha1m (>/=7.0 microgram/min) or IgG (>/=5.0 microgram/min) were detected in nine (12%), nine (12%) and 11 patients (14%), respectively. Latent or overt distal renal tubular acidosis (dRTA) was observed in 18 out of 55 patients with pSS (33%). These patients had a longer duration of the disease (10+/-4 vs 8+/-4 yr; P+info)

Autosomal recessive distal renal tubular acidosis associated with Southeast Asian ovalocytosis. (3/246)

BACKGROUND: A defect in the anion exchanger 1 (AE1) of the basolateral membrane of type A intercalated cells in the renal collecting duct may result in a failure to maintain a cell-to-lumen H+ gradient, leading to distal renal tubular acidosis (dRTA). Thus, dRTA may occur in Southeast Asian ovalocytosis (SAO), a common AE1 gene abnormality observed in Southeast Asia and Melanesia. Our study investigated whether or not this renal acidification defect exists in individuals with SAO. METHODS: Short and three-day NH4Cl loading tests were performed in 20 individuals with SAO and in two subjects, including their families, with both SAO and dRTA. Mutations of AE1 gene in individuals with SAO and members of the two families were also studied. RESULTS: Renal acidification in the 20 individuals with SAO and in the parents of the two families was normal. However, the two clinically affected individuals with SAO and dRTA had compound heterozygosity of 27 bp deletion in exon 11 and missense mutation G701D resulting from a CGG-->CAG substitution in exon 17 of the AE1 gene. Red cells of the two subjects with dRTA and SAO and the family members with SAO showed an approximate 40% reduction in sulfate influx with normal 4,4'-di-isothiocyanato-stilbene-2,2'-disulfonic acid sensitivity and pH dependence. CONCLUSION: These findings suggest that compound heterozygosity of abnormal AE1 genes causes autosomal recessive dRTA in SAO.  (+info)

Localization of a gene for autosomal recessive distal renal tubular acidosis with normal hearing (rdRTA2) to 7q33-34. (4/246)

Failure of distal nephrons to excrete excess acid results in the "distal renal tubular acidoses" (dRTA). Early childhood features of autosomal recessive dRTA include severe metabolic acidosis with inappropriately alkaline urine, poor growth, rickets, and renal calcification. Progressive bilateral sensorineural hearing loss (SNHL) is evident in approximately one-third of patients. We have recently identified mutations in ATP6B1, encoding the B-subunit of the collecting-duct apical proton pump, as a cause of recessive dRTA with SNHL. We now report the results of genetic analysis of 13 kindreds with recessive dRTA and normal hearing. Analysis of linkage and molecular examination of ATP6B1 indicated that mutation in ATP6B1 rarely, if ever, accounts for this phenotype, prompting a genomewide linkage search for loci underlying this trait. The results strongly supported linkage with locus heterogeneity to a segment of 7q33-34, yielding a maximum multipoint LOD score of 8.84 with 68% of kindreds linked. The LOD-3 support interval defines a 14-cM region flanked by D7S500 and D7S688. That 4 of these 13 kindreds do not support linkage to rdRTA2 and ATP6B1 implies the existence of at least one additional dRTA locus. These findings establish that genes causing recessive dRTA with normal and impaired hearing are different, and they identify, at 7q33-34, a new locus, rdRTA2, for recessive dRTA with normal hearing.  (+info)

NH4+ secretion in inner medullary collecting duct in potassium deprivation: role of colonic H+-K+-ATPase. (5/246)

NH4+ secretion in inner medullary collecting duct in potassium deprivation: Role of colonic H+-K+-ATPase. BACKGROUND: In K+ deprivation (KD), gastric (g) H+-K+-ATPase (HKA) is suppressed, whereas colonic (c) HKA is induced in the terminal inner medullary collecting duct (IMCD). We hypothesized that in KD, cHKA is induced and can mediate the secretion of NH4+. METHODS: Rats were sacrificed after 2, 3, 6, or 14 days on regular (NML) or K+-free (KD) diet. mRNA expression of HKA isoforms in terminal inner medulla was examined and correlated with NH4+ secretion in perfused IMCD in vitro. RESULTS: Urinary NH4+ excretion increased after K+-free diet for six days. In terminal inner medulla, cHKA expression was strongly induced, whereas gHKA expression was decreased. NH4+ secretion increased by 62% in KD (JtNH4+ 0.57 vs. 0.92 pmol/min/mm tubule length, P < 0.001). Ouabain (1 mM) in perfusate inhibited NH4+ secretion in KD by 45% (P < 0.002) but not in NML. At luminal pH 7.7, which inhibits NH3 diffusion, NH4+ secretion in IMCD was 140% higher in KD (0.36 vs. 0.15, P < 0.03) and was sensitive to ouabain. ROMK-1 mRNA expression was induced in parallel with cHKA in inner medulla. CONCLUSIONS: These data suggest that in KD, cHKA replaces gHKA and mediates enhanced secretion of NH4+ (and H+) into the lumen facilitated by K+ recycling through ROMK-1.  (+info)

Study of urinary acidification in patients with idiopathic hypocitraturia. (6/246)

Hypocitraturia (HCit) is one of the most remarkable features of renal tubular acidosis, but an acidification defect is not seen in the majority of hypocitraturic patients, whose disease is denoted idiopathic hypocitraturia. In order to assess the integrity of urinary acidification mechanisms in hypocitraturic idiopathic calcium stone formers, we studied two groups of patients, hypocitraturic (HCit, N = 21, 39.5 +/- 11.5 years, 11 females and 10 males) and normocitraturic (NCit, N = 23, 40.2 +/- 11.7 years, 16 females and 7 males) subjects, during a short ammonium chloride loading test lasting 8 h. During the baseline period HCit patients showed significantly higher levels of titratable acid (TA). After the administration of ammonium chloride, mean urinary pH (3rd to 8th hour) and TA and ammonium excretion did not differ significantly between groups. Conversely, during the first hour mean urinary pH was lower and TA and ammonium excretion was higher in HCit. The enhanced TA excretion by HCit during the baseline period and during the first hour suggests that the phosphate buffer mechanism is activated. The earlier response in ammonium excretion by HCit further supports other evidence that acidification mechanisms react promptly. The present results suggest that in the course of lithiasic disease, hypocitraturia coexists with subtle changes in the excretion of hydrogen ions in basal situations.  (+info)

Hypokalaemic paralysis. (7/246)

Hypokalaemic paralysis is a relatively uncommon but potentially life-threatening clinical syndrome. If recognised and treated appropriately, patients recover without any clinical sequellae. The syndrome of hypokalaemic paralysis represents a heterogeneous group of disorders characterised clinically by hypokalaemia and acute systemic weakness. Most cases are due to familial or primary hypokalaemic periodic paralysis; sporadic cases are associated with numerous other conditions including barium poisoning, hyperthyroidism, renal disorders, certain endocrinopathies and gastrointestinal potassium losses. The age of onset, race, family history, medications, and underlying disease states can help in identifying the cause of hypokalaemic paralysis. Initial therapy of the patient with hypokalaemic paralysis includes potassium replacement and search for underlying aetiology. Further management depends on the aetiology of hypokalaemia, severity of symptoms, and duration of disease. This review presents the differential diagnosis for hypokalaemic paralysis and discusses management of the syndrome.  (+info)

Renal involvement in primary Sjogren's syndrome. (8/246)

Renal involvement was evaluated in 62 patients with primary Sjogren's syndrome, classified according to criteria proposed by The European Classification Criteria Group. Urine concentration capacity was tested using intranasal 1-desamino-8-D-arginine-vasopressin. For patients with urine pH>5.5 without metabolic acidosis (n=28), an acidification test with ammonium chloride was performed. Urinary citrate, albumin, NAG, ALP and beta2-microglobulin were measured and creatinine clearance was calculated. Maximum urine concentration capacity and creatinine clearance were reduced in 13 (21%). Albumin excretion was >30 microg/min in only one patient (1.6%). Seven patients (11.3%) had complete or incomplete distal renal tubular acidosis (dRTA), four had reduced creatinine clearance and five had reduced maximum urine concentration capacity. The ratio of citrate/creatinine in spot urine was below the 2.5 percentile in all patients with complete or incomplete dRTA. The prevalence of dRTA was lower than in previous studies. There were also few patients with signs of glomerular disease (1.6%). The use of citrate:creatinine ratio in spot urine can be a helpful method in identifying patients with complete or incomplete dRTA.  (+info)

Distal renal tubular acidosis is a rare renal tubular disorder characterized by hyperchloremic metabolic acidosis and impaired urinary acidification. Mutations in three genes (ATP6V0A4, ATP6V1B1 and SLC4A1) constitute a monogenic causation in 58-70% of familial cases of distal renal tubular acidosis. Recently, mutations in FOXI1 have been identified as an additional cause. Therefore, we hypothesized that further monogenic causes of distal renal tubular acidosis remain to be discovered. Panel sequencing and/or whole exome sequencing was performed in a cohort of 17 families with 19 affected individuals with pediatric onset distal renal tubular acidosis. A causative mutation was detected in one of the three "classical" known distal renal tubular acidosis genes in 10 of 17 families. The seven unsolved families were then subjected to candidate whole exome sequencing analysis. Potential disease causing mutations in three genes were detected: ATP6V1C2, which encodes another kidney specific subunit of ...

What does renal tubular acidosis, distal, autosomal dominant mean?
SLC4A1-associated distal renal tubular acidosis is a kidney (renal) disorder that sometimes includes blood cell abnormalities. The kidneys normally filter fluid and waste products from the body and remove them in urine; however, in people with distal renal tubular acidosis, the kidneys are unable to remove enough acid from the body, and the blood becomes too acidic. This chemical imbalance is called metabolic acidosis. The inability to remove acids from the body often results in slowed growth and may also lead to softening and weakening of the bones, called rickets in children and osteomalacia in adults.. This bone disorder is characterized by bone pain, bowed legs, and difficulty walking. In addition, most children and adults with SLC4A1-associated distal renal tubular acidosis have excess calcium in the urine (hypercalciuria), calcium deposits in the kidneys (nephrocalcinosis), and kidney stones (nephrolithiasis). In rare cases, these kidney abnormalities lead to life-threatening kidney ...
Distal renal tubular acidosis (dRTA) or Type 1 renal tubular acidosis (RTA) is the classical form of RTA, being the first described. Distal RTA is characterized by a failure of acid secretion by the alpha intercalated cells of the cortical collecting duct of the distal nephron. This failure of acid secretion may be due to a number of causes, and it leads to an inability to acidify the urine to a pH of less than 5.3. Because renal excretion is the primary means of eliminating acid from the body, there is consequently a tendency towards acidemia. This leads to the clinical features of dRTA: Normal anion gap metabolic acidosis/acidemia Hypokalemia Urinary stone formation (related to alkaline urine, hypercalciuria, and low urinary citrate). Nephrocalcinosis (deposition of calcium in the substance of the kidney) Bone demineralisation (causing rickets in children and osteomalacia in adults) The symptoms and sequelae of dRTA are variable and range from being completely asymptomatic, to loin pain and ...
TY - JOUR. T1 - Hypokalemic Distal Renal Tubular Acidosis. AU - Vallés, Patricia G.. AU - Batlle, Daniel. PY - 2018/7. Y1 - 2018/7. N2 - Distal renal tubular acidosis (DRTA) is defined as hyperchloremic, non-anion gap metabolic acidosis with impaired urinary acid excretion in the presence of a normal or moderately reduced glomerular filtration rate. Failure in urinary acid excretion results from reduced H+ secretion by intercalated cells in the distal nephron. This results in decreased excretion of NH4 + and other acids collectively referred as titratable acids while urine pH is typically above 5.5 in the face of systemic acidosis. The clinical phenotype in patients with DRTA is characterized by stunted growth with bone abnormalities in children as well as nephrocalcinosis and nephrolithiasis that develop as the consequence of hypercalciuria, hypocitraturia, and relatively alkaline urine. Hypokalemia is a striking finding that accounts for muscle weakness and requires continued treatment ...
Both the autosomal dominant and autosomal recessive forms of SLC4A1-associated distal renal tubular acidosis are caused by mutations in the SLC4A1 gene. This gene provides instructions for making the anion exchanger 1 (AE1) protein, which transports negatively charged atoms (anions) across cell membranes. Specifically, AE1 exchanges negatively charged atoms of chlorine (chloride ions) for negatively charged bicarbonate molecules (bicarbonate ions). The AE1 protein is found in the cell membrane of kidney cells and red blood cells. In kidney cells, the exchange of bicarbonate through AE1 allows acid to be released from the cell into the urine. In red blood cells, AE1 attaches to other proteins that make up the structural framework (the cytoskeleton) of the cells, helping to maintain their structure.. The SLC4A1 gene mutations involved in either form of SLC4A1-associated distal renal tubular acidosis lead to production of altered AE1 proteins that cannot get to the correct location in the cell ...

Introduction: Distal renal tubular acidosis is a rare genetic disease, characterised by deficit in renal tubular transport. Clinical features are metabolic acidosis with hypercloraemia and hypokalemia, and inability in urine acidification. Hypercalciuria may also be present, often treated with the use of a diuretic therapy with thiazides. Case Presentation: We present a severe disease onset in a neonate with consanguineous parents, both autosomal-recessive for an ATP6VOA4 gene mutation, and a nevertheless severe episode of metabolic alkalosis, occurred in the same patient after few months, during the diuretic therapy. Conclusion: Biochemical results lead us to hypothesize a susceptibility to the treatment that need further investigations. ...

Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine. In renal physiology, when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron, allowing for exchange of salts, acid equivalents, and other solutes before it drains into the bladder as urine. The metabolic acidosis that results from RTA may be caused either by failure to reabsorb sufficient bicarbonate ions (which are alkaline) from the filtrate in the early portion of the nephron (the proximal tubule) or by insufficient secretion of hydrogen ions (which are acidic) into the latter portions of the nephron (the distal tubule). Although a metabolic acidosis also occurs in those with renal insufficiency, the term RTA is reserved for individuals with poor urinary acidification in otherwise well-functioning kidneys. Several different types of RTA exist, which all have different syndromes and ...

Some of them exhibit brain function-related symptoms, such as migraine and mental retardation, but physiological roles of NBCe1 in brain function remain unclear. To gain insights into NBCe1-specific functions in the brain, we herein identified proteins that specifically bind to a unique C-terminal region of NBCe1-C, a brain-specific NBCe1 isoform. We found that a catalytic subunit of calcineurin binds to the C terminus of NBCe1-C in the mouse cerebellum. Heterologous-coexpression experiments revealed that calcineurin binds to NBCe1-C via a "PQIRIE" motif at its C terminus. The interaction enhanced cell surface expression of NBCe1-C, resulting in an increase of its transporter activity, for which the ...
Hi. I was diagnosed with RTA type 4 when I was 2 years old. My mom took me to a neurologist because I hadnt started walking yet. They did blood work, and found that my potassium was too high. So, I started going to a nephrologist. They found, through extensive blood work that what worked best for me was the medicine hyrdrochlorothiazide. I have to take this every day, or my potassium will go up. About five years ago, my brother was getting blood work done to see if he qualified for accutane, and they found that his potassium was dangerously high. He spent about a week in the hospital. They found he had a heart arrythmia. And he was finally diagnosed with pseudohyperaldosterone type1. It appears that this is a genetic abnormality within my family. I will be getting my 2 sons tested as well ...
Renal calculi can develop in any part of urinary tract but mostly found in renal pelvis or in calyces. Renal calculi are also known as kidney stones, these are solid crystals aggregation formed in the kidneys from the dietary minerals present in the urine. These stones are mainly located in the kidney, ureter, and bladder. Read more ...

Mutations of SLC4A1 (AE1) encoding the kidney anion (Cl(-)/HCO(3) (-)) exchanger 1 (kAE1 or band 3) can result in either autosomal dominant (AD) or autosomal recessive (AR) distal renal tubular acidosis (dRTA). The molecular mechanisms associated with SLC4A1 mutations resulting in these different modes of inheritance are now being unveiled using transfected cell systems. The dominant mutants kAE1 R589H, R901X and S613F, which have normal or insignificant changes in anion transport function, exhibit intracellular retention with endoplasmic reticulum (ER) localization in cultured non-polarized and polarized cells, while the dominant mutants kAE1 R901X and G609R are mis-targeted to apical membrane in addition to the basolateral membrane in cultured polarized cells ...
Karin Finberg received her B.S., M.D., and Ph.D. degrees from Yale. Her Ph.D. dissertation with Dr. Richard Lifton in the Department of Genetics focused on the genetic basis of an autosomal recessive disorder of systemic pH homeostasis, distal renal tubular acidosis with sensorineural deafness. After graduating from Yale, Karin completed residency training in Clinical Pathology at Massachusetts General Hospital and clinical fellowship training in the Harvard Medical School Molecular Genetic Pathology Training Program based at Brigham and Womens Hospital. She then completed postdoctoral research training in the laboratory of Dr. Nancy Andrews, first at Childrens Hospital Boston and later at Duke University Medical Center, where she employed genetic study of patients with an inherited form of iron deficiency anemia to shed insight into mechanisms of systemic iron regulation. In her research laboratory at Yale, Karin continues to investigate mechanisms of iron balance through genetic study of ...
Cisplatin (CP) is commonly used in the treatment of different types of cancer but nephrotoxicity has been a major limiting factor. Therefore, the present study aimed to study the possible protective effect of rutin against nephrotoxicity induced by cisplatin in rats. Forty male Wistar albino rats were randomly divided into 4 groups. Rats of group 1 control group intraperitoneal (i.p.) received 2.5 ml/kg, group 2 CP group received single dose 5 mg/kg cisplatin i.p. group 3 rutin group orally received 30 mg/kg rutin group 4 (CP plus rutin) received CP and rutin as in group 2 and 3. Kidneys were harvested for histopathology and for the study the gene expression of c-Jun N-terminal kinases (JNK), Mitogen-activated protein kinase 4 (MKK4), MKK7, P38 mitogen-activated protein kinases (P38), tumor necrosis factors alpha (TNF-α), TNF Receptor-Associated Factor 2 (TRAF2), and interleukin-1 alpha (IL-1-α).

The urinary anion gap is key to determining if the non-gapped metabolic acidosis is GI or renal. The urinary anion gap provides an estimate of the urinary ammonium (NH4+) excretion. The urinary anion gap is defined as UAG = Unmeasured Anion (UA) - Unmeasured Cation (UC). As seen in diarrhea, bicarbonate is excreted via the gut triggering urinary ammonium excretion to maintain electroneutrality. This causes an increased UC (urinary NH4+) and results in a negative UAG. On the other hand, renal tubular acidosis involve the inability of the kidney to resorb bicarbonate. This causes an increased UA (urinary HCO3-) and results in a positive UAG.. It is worthy to understand how the urinary anion gap was derived. The cations present in urine include: Na+, K+, Ca2+, Mg. The anions in urine include: Cl-, HCO3-, sulfate, phosphate and some organic acids. Only Na+, K+, Cl- are typically measured in urine.. By law of electroneutrality we have the equation: Na+ + K+ + UC = Cl- + UA; UC: unmeasured cations; ...
Renal tubular acidosis (1), an impairment of renal acid excretion out of proportion to reduction of glomerular filtration rate, has been described in a variety of clinical settings. Its characteristic clinical manifestations are hyperchloremic acidosis, an inability to excrete a highly acid urine, and impaired renal concentrating ability. It may be associated, in the primary form, with renal calculi, nephrocalcinosis, osteomalacia, and potassium depletion (2). Subclinical cases-either asymptomatic or lacking the laboratory findings of the overt cases of renal tubular acidosis-have been uncovered by an acid-loading test designed to detect acid excretion inappropriate to the induced metabolic acidosis (3, 4). ...

Calcium deposits in veins - What are calcium deposits in the urine? Sometimes the level. Of calcium in the urine or blood is so high that it precipitates and forms deposits in the kidney called nephrocalcinosis. The is related to, but not the same as kidney stones. It can be caused by several genetic syndromes, hyperparathyroidism and vitamin D toxicity, certain meds, TB, renal tubular acidosis, etc. It is usually managed by treated the underlying condition. Good wishes:)
An accurate history and careful examination will determine the sequence and spectrum of clinical investigations required to make a diagnosis or decide on prognosis or treatment.Midstream urine (MSU) sample-this standard investigation requires consideration of: (1) macroscopic appearance-this may be suggestive of a diagnosis, e.g. frothy urine suggests heavy proteinuria; (2) stick testing-including for pH (<5.3 in an early-morning specimen makes a renal acidification defect unlikely), glycosuria, specific gravity (should be >1.024 in an early-morning or concentrated sample), nitrite (>90% of common urinary pathogens produce nitrite) and leucocyte esterase; and (3) microscopy-for cellular elements (in particular red cells, with the presence of dysmorphic red cells detected by experienced observers indicative of glomerular bleeding), casts (cellular casts indicate renal inflammation), and crystals....
This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of intracellular compartments of eukaryotic cells. V-ATPase dependent acidification is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The V1 domain contains the ATP catalytic site. The V0 domain consists of five different subunits: a, c, c, c, and d. This gene is one of four genes in man and mouse that encode different isoforms of the a subunit. Alternatively spliced transcript variants encoding the same protein have been described. Mutations in this gene are associated with renal tubular acidosis associated with preserved hearing. [provided by RefSeq, Jul 2008] ...
The Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease (CKD) has defined CKD as abnormalities of kidney structure or function, present for more than 3 months, with implications for health. Structural or functional abnormalities may manifest by markers of kidney damage and/or glomerular filtration rate (GFR) less than 60 mL/min/1.73 m2 of body surface area. Markers of kidney damage include albuminuria greater than or equal to 30 mg/24 h (or ≥30 mg/g by albumin/creatinine ratio), urine sediment abnormalities (ie, microscopic hematuria), electrolyte and other abnormalities due to tubular disorders (ie, renal tubular acidosis), abnormalities detected by histology (ie, chronic glomerulonephritis) or imaging studies (ie, polycystic kidneys), or history of kidney transplantation. GFR can be estimated from serum creatinine or cystatin C with a formula, preferably the chronic kidney disease-epidemiology collaboration ...

As Nate mentioned in a previous post, the urinary anion gap is helpful in differentiating whether a non-gap acidosis is of renal or extra-renal origin.. Urinary Anion Gap = Na + K - Cl. Because the major cation in the urine is NH4, this gives you a rough estimate of the NH4 level. In the setting of a distal RTA, the urine NH4 should be low and therefore there should be a positive anion gap. The problem with this test is that if there is some other unmeasured anion (e.g. ketoacids or hippurate following glue-sniffing) or even if the patients diet leads to significant changes in PO4 or SO4 excretion, it can be very inaccurate. One alternative suggested by Mitch Halperin is to measure the urinary osmolar gap. This is more useful because it detects the NH4 excretion regardless of the anion that is excreted along with it. Urine Osmolar Gap = measured Uosm - calculated Uosm. Calculated Uosm = 2(Na + K) + Urea (mmol) + Glucose (mmol). Because the other major cation in the urine is NH4 and this must be ...

Two male patients were found to have Southeast Asian ovalocytosis - one incidentally and the other one during the investigations of the aetiology for hypokalemic paralysis. Southeast Asian ovalocytosis is found almost exclusively in Southeast Asia (1, 2). Familial renal tubular acidosis can co-exist with south East Asian ovalocytosis in the same patient (2). Anionexchanger 1 gene AE1 mutation is the underlying pathology and both can originate from the same mutation (2). This can be asymptomatic as in case 1 and can be symptomatic as in case 2. Symptomatic patients need oral potassium and bicarbonate replacement and follow up. After initial clinical assessment and investigations of case 2, he was given intravenous potassium replacement. The correction of metabolic acidosis was made by giving oral sodium bicarbonate 600mg twice daily. Eventually he made full recovery and did not develop further similar episodes ...
The aim of this study was to identify the causative mutation in a family with an unusual presentation of autosomal dominant osteopetrosis (OPT), proximal renal tubular acidosis (RTA), renal stones, epilepsy, and blindness, a combination of features not previously reported. We undertook exome sequencing of one affected and one unaffected family member, followed by targeted analysis of known candidate genes to identify the causative mutation. This identified a missense mutation (c.643G|A; p.Gly215Arg) in the gene encoding the chloride/proton antiporter 7 (gene CLCN7, protein CLC-7), which was confirmed by amplification refractory mutation system (ARMS)-PCR, and to be present in the three available patients. CLC-7 mutations are known to cause autosomal dominant OPT type 2, also called Albers-Schonberg disease, which is characterized by osteosclerosis, predominantly of the spine, pelvis and skull base, resulting in bone fragility and fractures. Albers-Schonberg disease is not reported to be associated with
Respiratory paralysis due to renal tubular acidosis (RTA) is rare. We report a 22-year-old lady who developed severe bulbar, respiratory and limb paralysis following respiratory infection. She had hypokalemia (1.6 meq/L) and hyperchloremic (110 meq/l
Introduction Acute metabolic acidosis of non-renal origin is usually a result of either lactic or ketoacidosis, both of which are associated with a high anion gap. There is increasing recognition, however, of a group of acidotic patients who have a large anion gap that is not explained by either keto- or lactic acidosis nor, in most cases, is inappropriate fluid resuscitation or ingestion of exogenous agents the cause. Methods Plasma ultrafiltrate from patients with diabetic ketoacidosis, lactic acidosis, acidosis of unknown cause, normal anion gap metabolic acidosis, or acidosis as a result of base loss were examined enzymatically for the presence of low molecular weight anions including citrate, isocitrate, ?-ketoglutarate, succinate, malate and d-lactate. The results obtained from the study groups were compared with those obtained from control plasma from normal volunteers. Results In five patients with lactic acidosis, a significant increase in isocitrate (0.71 ± 0.35 mEq l-1), ...
